Abstract:Results are presented from a microbiological (bacteriological and mycological) investigation and the sensitivity tests of microorganisms isolated over a 2-year period (1983-84) from 80 fecal samples and 466 necropsies of psittacine birds. These results are correlated with signs of metaplasia of the salivary glands due to vitamin A deficiency in large parrots and with low vitamin A levels in the livers of small psittacine birds. Aerobic microorganisms were isolated from 76% of the fecal samples and 67% of the necropsies. Infections with primary pathogenic bacteria were found in less than 10% of the necropsies. Metaplasia was found in 51% of the large parrots, and the vitamin A levels in budgerigars were below acceptable levels. The possible role of a deficient diet in Psittaciformes in the occurrence of microbial infections and their treatment are discussed. /// Se presentan los resultados de investigación de una encuesta microbiológica (bacteriológica y micológica) y las pruebas de sensibilidad de los microorganismos aislados durante un período de 2 años (1983-1984) a partir de 80 muestras de materia fecal y 466 necropsias de aves psitácidas. Estos resultados se asocian a los signos de metaplasia de las glándulas salivares debido a la deficiencia de vitamina A en papagallos y a niveles bajos de vitamina A en el hígado de psitácidas pequeñas. Microorganismos aerobios fueron aislados del 76% de las muestras de materia fecal y 67% de las necropsias. En menos del 10% de las necropsias se encontraron infecciones causadas primariamente por bacterias patógenas. Se encontró metaplasia en el 51% de los papagallos y los niveles de vitamina A en periquitos estaban por debajo de los niveles aceptados. Se discute el papel que juega una dieta deficiente en Psittaciformes sobre la presentación de infecciones microbianas y su tratamiento.
